This invention relates to a gate.

An object of the present invention is to provide a gate for road wayswhich will be normally maintained in closed position, but which may bereadily opened by a motor vehicle, to permit passage of the vehicle andwhich will automatically close; accordingly the gate has beenconstructed and mounted so that it may be opened in either direction.

It is another object of the invention to provide what is commonly knownas a ranch-type gate and which is necessarily of rather heavyconstruction, but which includes means for checking, or retarding, themomentum of the gate as it swings toward closed position to preventinjury to the gate should it strike an object while swinging closed.

The invention also embodies a. trolly actuated latching and unlatchingdevice which is mounted on the gate.

A still further object of the invention is to provide a gate of thecharacter described embodying novelly designed and arranged push, orbumper, plates.

The invention also comprehends a novel type of adjustable hinge formounting the gate.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts an example of which is given in this specificationand illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of the gate shown in closed position andpartly in section.

- Figure 2 is a vertical sectional view taken on the line 2-2 of Figure1.

Figure 3 is a vertical sectional view taken on the line 33 of Figure l.

Figure 4 is a side elevation of the gate shown in open position.

Figure 5 is an elevational view of a latch post employed.

Figure 6 is a rear elevational view of the gate latching mechanismshowing the gate roller approaching latched position.

Figure 7 is a rear elevation thereof showing the roller in final latchedposition.

Figure 8 is a top plan view of the gate also showing the gate partiallyopen in dotted lines and Figure 9 is a diagrammatic plan view, on areduced scale, showing the gate closed in full lines and in open andintermediate positions in dotted lines.

Referring now more particularly to the draw- 3 Claims. (Cl. 39-31) ingswherein lik numerals of reference designate the same parts in each ofthe figures the numerals I and 2 designate the top and bottom bars,respectively, of the gate.

In the present illustration these bars are secured, at their rear ends,to the upper and lower ends, respectively, of the rear end bar 3. Thelower end of the bar 3 is extended beneath the bottom bar 2 and isformed into a round spindle 4.

Y The forward ends of the top and bottom bars I and 2 are securedbetween the upper and lower ends, respectively, of the angle irons 5which are spaced apart and which form the front bar of the gate.

The parts hereinabove described are preferably formed of metal and maybe welded or otherwise secured together.

The gate is hinged to an upstanding post 6 in th following manner: theexternally threaded shank I of an eye bolt is extended through the post6 near the lower end thereof and is clamped thereto by the clamp nuts 8,8 threaded on said shank I and the spindle 4 is fitted through the eyeof said bolt. There is a U-bolt 9 whose shanks are externally threadedand extended through the top of the post 6 and are clamped thereto by,the clamp nuts I0, III which are threaded onto the shanks of the U-bolt9 as shown in Figures 1 and 8. Welded to the top bar I near its rear endthere is a tubular anchor I I and fitted through this anchor there isthe outwardly threaded shank of an eye bolt I2 Which is clamped inpositionby the clamp nuts I3, I3. The eye of the bolt I2 is elongated asbest shown in Figure 8 and the U-bolt 9. is linked through it. Thiselongated eye allows the forward end of the gate to have alimited rangeof vertical movement.

Out beyond the. free or forward endof the gate there isthe upstandinggate post I4 which is provided with a rearwardly extended stop I5 andbeneath said stop there is a latch plate I6 having an upwardly flarednotch I! provided with theguidefaces I8, I8 and on each sideof said'notch'said latch plate I6 is provided with the downwardly divergingguide ways I9, I9.

The forward end of the bottom bar 2 of the gate is extended beyond thefront bar 5 and is formed into a spindle 29 on which the roller 2| isretained by a suitable retainer such as a cottcr key 22.

When the gate is in normal, or closed, position the roller M will restin the notch II beneath the stop I5,as shown in Figures 1 and 7. Uponlateral pressure being exerted against the gate the roller 2| will rideup along the opposing face l8 and out of the notch l1 and the gate maybe swung open. On the other hand as th gate swings toward closedposition the roller 2| will ride up along the corresponding guideway l9correspondingly elevating the forward or free end of the gate. This ispermitted by reason of the oblong eye of the eye bolt 12. In order toprevent the momentum of the gate from carrying the roller 2| across thenotch ll the stop !5 has been positioned so that the roller 21 will comeinto contact with it as shown in Figure 6 and the closing movement ofthe gate will be stopped and the roller 21 will drop down into, and beretained in, the notch IT, as indicated in Figure '7.

Particular attention here called to the double adjustment provided inthe top hinge arrangement. The eye bolt I and the spindle 4 forming thelower hinge are set at the desired location relative to the gate andfixed in such a position by the clamp nuts 8 and remain in thatposition, but it may be necessary to adjust the top hinge arrangement.Therefore the clamp nuts I!) may be loosened and the U-bolt 9 adjustedoutwardly so as to carry the hinge point further from the gate post 6and this will change the angular rep lation of the gate relative to thepost, when the gate is open, so that the gate will have a greatergravity momentum when swinging to closed position. On the other hand itmay be adjusted closer to the post 6 so that the gate will have lessgravity momentum when swinging to closed position. In making theseadjustments if the gate should not be exactly horizontal when in itsclosed position this may be corrected by a suitable adjustment of theeye bolt l2 relative to the anchor ll so as to bring the gate to thedesired horizontal position.

The numeral 23 designates a longitudinal tubular track which declinesslightly forwardly, when the gate is closed. Welded or otherwise securedto the track are the hangers 24, 25. The hanger 24 is fitted into asocket 26 welded to the rear end bar 3 and the hanger 25 projectsbetween the angle bars 5, 5, at the forward end of the gate, and iclamped in any desired position by means of the clamp bolts 21, 21extending transversely through said bars. The pitch of the track 23 maybe varied as desired by loosening the clamp bolts 21 and adjusting theforward end of the track up or down and then again tightening said clampbolts.

A trolley frame as 28 embraces said track 23 and mounted therein are thetrolley wheels 29, 29 which are grooved to move along said track. Theframe is extended each way forming the rear and front bumpers 30, BI.

Extended through the track 23 there is a latch rod 32 whose rear end isformed with the downwardly turned stop 33 and whose forward end isformed with the downwardly extended stop 34 and is extended beyond thestop 34 to work between the angle irons 5 thus forming a latch bolt 35.

Located approximately 90, each way, from the post M there are the checkposts 36, 36 which are located in substantial alignment with the upperhinge point of the gate. A crank shaped check latch 3'! is pivotallymounted in a transverse bearing 38 mounted on the forward side of eachcheck post at its upper end. The forward end 39 of this latch isupwardly turned and its other end 40, is downwardly turned and isengageable with a stop 50 on the corresponding post- The downwardlyturned, end of the l h 3'! is somewhat heavier than the upwardly turnedend so that the forward end 39 will normally stand in verticalrposition.When the gate is closed the trolley will be at the forward or free endof the gate and the front bumper 3|, acting against the forward stop 34will hold the latch bolt 35 projecting forward as shown in Figures 1 and8. When the gate is swung open the latch bolt 35 will engage theupturned end 39 which will be retracted by it and the gate will swing onto its entire open position as shown by dotted lines in Figure 9. Thetrolley will be maintained, by centrifugal force, in said last namedposition and when the gate reaches its fully open position it willimmediately start its return movement and the trolley will still bemaintained in said position at the forward or free end of the gate thusholding the latch bolt 35 extended and said latch bolt will engageagainst the upturned end 39 of the latch 31 and the downwardly turnedend 40 will engage against the stop 59 to hold the upturned end 39 inits vertical position and this will stop the return movement of thegate; but in this position the gate will decline toward its hinged end,as shown in Figure 4, and the trolley will travel, under the influenceof gravity, down the track 23 and the rear bumper 30 will engage thestop 33 and will move the rod 32 rearwardly thus withdrawing the latchbolt 35 from the upturned end 39, and the gate will then be free toswing on to closed position but the momentum of it will be checked, orretarded, so that the gate will not be liable to suffer any substantialinjury should it strike an object While closing. When the gate reachesclosed position the roller 2| will drop into the notch I! in the mannerhereinabove explained.

The gate is equipped with a novel type of push, or bumper, plates 5|,5!, one being arranged on each side. At their forward ends they areanchored, in spaced relation to the gate, by means of the front and rearbrackets 52 and 53. From the rear bracket 53 the plates converge to therear end bar 3 to which they are secured.

When a motor vehicle approaches the gate its front bumper 54 will comeinto contact with the parallel portion of the corresponding bumper plate5|, as illustrated in Figure 8, and the gate will be forced open. It isto be here noted that these bumper plates decline from the bar 3 to theangle irons 5, as shown in Figures 1 and 4 and as the gate swings openits free end will gradually rise, as indicated in Figure 4,- so as tokeep the bumper plate approximately aligned with the vehicle bumper andas the vehicle passes on throughthe gate the end of the bumper on thesame side of the road as the gate will come into contact with therearwardly converging portion of the bumper plate, as indicated indotted lines in Figure 8, and will impart additional momentum to thegate to swing it fully open and the return movement of the gate will betemporarily checked by the upturned end 39 of the check latch, ashereinabove explained so that the vehicle will have ample time to clearthe return path of the gate before the check latch is released by thetrolley and the gate swings on toward closed position.

When the gate is closed the trolley will again move to the forward orfree end of the gate and will project the latch bolt 35 forwardly asshown in Figures 1 and. 8.

The drawings, and description are illustrative merely while the broadprinciple of the invention will be defined by the appended claims.

What I claim is:

1. A gate substantially rectangular in shape and having top and bottombars and end bars, a longitudinal tubular track whose ends are connectedto the end bars of the gate, a latch rod slidably mounted in said trackand having end stops and one end of which terminates in a latch bolt, atrolley movable along the track and having bumpers thereon engageablewith said stops and efiective to move the rod into one position toretract the latch bolt into inactive position and to move said latch rodto another position to extend the latch bolt into active position.

2. The combination with spaced gate posts, of a gate between the posts,means for mounting one end of the gate on one post whereby the gate mayswing laterally to open or closed position, a latch bolt projecting fromthe free end of the gate, a check post, a latch on the check post whichis retractable to inactive position by the latch bolt as the gate swingsto open position, said latch being arranged to engage the latch boltupon return movement of the gate to check (7 to contact with said latchand to move the latch to retracted position as the gate moves towardopen position, said latch bolt being arranged to engage the latch tocheck the movement of the gate toward closed position and a trolley onthe gate movable by gravity to disengage said latch bolt from the latchto allow the gate to swing on to closed position.
